Previous research has evaluated the effects of prompt rates on the rate of communicative behavior. More recent research has suggested that dense prompting can result in communicative behavior that is more resistant to change. However, existing research has not considered the impact that higher response rates had on reinforcement rate, a variable known to impact response persistence. The current study systematically replicated previous research by evaluating communicative responding in contexts associated with dense- and lean-prompt schedules and extended existing research by (a) holding reinforcement rates similar across the two prompting schedules (lean and dense), and (b) evaluating the persistence of communicative responding in the contexts associated with each prompting schedule. The results for Experiment 1 clearly replicated and extended previous research. The results for Experiment 2 were equivocal and suggested that previous reinforcement history and response class size impacted outcomes. 相似文献

Prosumers are individuals who produce goods they consume themselves. The prosumption literature suggests that prosumption can be enhanced through knowledge sharing, creativity and innovation, and developing expertise. In this article, we investigate the relationships between prosumption experiences, prosumption values, and affinity with a prosumption activity. We use a structural equation model approach to evaluate the relationships between these constructs and assume that affinity can mediate the relationship between prosumption experiences and values. We collect empirical data from prosumers who homebrew their own beer and confirm that prosumption experiences and values are positively related, and that affinity mediates the relationship between experiences and values. Implications deriving from these findings are discussed along with directions for future research. 相似文献

Massage techniques and postural manipulation used by West African women immigrants in Paris were studied, with the aim of demonstrating that culturally regulated caretaking practices have an influence on infant motor development. Twenty-five infants were observed between the ages of 3 and 12 months and 9 and 15 months. Frequency of massage and its accompanying set of physical exercises were found to be related to age at onset of independent walking. The findings show that infants receiving daily massage walk significantly earlier than infants who do not receive massage, thus confirming other reports that vestibular and postural stimulation have a positive effect on motor development. These results are discussed in relation to the observed frequencey of contact and of physical games with the caregiver for a smaller sample of three infants, and to parental expectations about the age of acquisition of certain cognitive and motor abilities. African immigrant mothers expect their infants to sit and to walk earlier than French mothers. The conclusion emphasizes the contribution of social anthropology, which shows that in all cultures, physical development and body changes elicit symbolic practices and a search for explanation. 相似文献

Although lexical semantic deficits are postulated to play a prominent role in the anomia of Alzheimer's disease, it is unclear whether the primary disturbance is one of lexical access or one of lexical semantic loss. Response consistency on a naming task is one means of evaluating the underlying source of naming impairment. Access dysfunction usually implies variable word-finding difficulty, while a theory of lexical loss predicts that many word names would be consistently unavailable. Nineteen Alzheimer's disease patients were administered a visual confrontation naming task (the Boston Naming Test) on two occasions 6 months apart. Eighty percent of errors occurred consistently at both times; only 20% of errors occurred on only one occasion. Response consistency occurred significantly more often than expected under the assumption of no response consistency. Findings support the hypothesis that anomia in Alzheimer's disease is in part due to a loss of lexical semantic information. 相似文献

The major challenge facing today’s biomedical researchers is the increasing competition for available funds. The competitive
review process, through which the National Institutes of Health (NIH) awards grants, is built upon review by a committee of
expert scientists. The NIH is firmly committed to ensuring that its peer review system is fair and objective.

In the area of child psychosocial intervention research, substantial progress in addressing challenging methodological issues has been made. In this article we suggest that continued movement forward requires maintaining a balance between methodological and theoretical issues, and that it would be advantageous to begin to think about matching advances in methodological sophistication by similar advances in theoretical sophistication. The need to advance our understanding of theoretical issues is especially important in light of the challenges raised by postmodernism, particularly as these challenges relate to knowledge development. We discuss these challenges and describe how a pragmatic orientation may be a useful way to respond to them. We also describe how a pragmatic orientation has been useful in our work in developing, implementing and evaluating psychosocial interventions for children with phobic and anxiety disorders. 相似文献

To identify reasons for discrepancies between parent and child reports of child/adolescents's psychiatric symptoms, parents and adolescents (51 pairs) were asked to guess what the other would answer to questions from the PC-DISC about the adolescent's psychiatric symptoms, and to explain why they expected disagreement when the answer they provided for the other was different from their own. Adolescents' explanations for expecting (1) parental denial of symptoms the adolescent reported were: the parent was unaware of, forgot about, assumed the adolescent could not have, or trivialized the symptom; and (2) parental report of symptoms the adolescent denied were: the parent misread or exaggerated the adolescent's symptom, had too high expectations for the adolescent's behavior, put a negative label on or did not trust the adolescent. Parents' reasons for expecting their children to (1) deny symptoms the parents reported were: the adolescent did not remember how s/he felt, lied, did not recognize or minimized the importance or frequency of the symptom; and (2) report symptoms the parents denied were: the adolescent lied, exaggerated the importance of or interpreted the symptom differently.Support for this work was provided by National Institute of Drug Abuse grant number DA-05585 (Dr. Cottler, P.I.), and National Institute of Mental Health grants numbers MH-31302 (Dr. R. C.

We examined the nature of referrals to a health center-based pediatric psychology service from 1990 to 1993 and assessed the satisfaction of health professionals with these services. Archival evaluation of 1467 records showed that over half of the consultation requests came from general pediatrics, pediatric neurology, and surgical services and that 70% of the psychological services were delivered on an outpatient basis. The most frequent referrals were for cognitive/neuropsychological evaluation and externalizing behavior problems. Pediatric psychology trainees were involved in 94% of the consultations. Survey of health professionals (n = 143) indicated very high overall satisfaction with the quality of services delivered. Presenting problems yielding the greatest likelihood for future consultation requests were behavior problems, child abuse, coping with illness, and depression/suicide. Results are discussed in the context of previous evaluations of pediatric psychology services and recommendations for future evaluation research. 相似文献

We reviewed the literature on the detection and management of mental health disorders within the context of pediatric primary care. Pediatricians have displayed a low sensitivity and high specificity in research investigating the detection of mental health impairment in children. Active management efforts characterize approaches to identified cases with more recently trained primary care pediatricians displaying a wider range of skills in managing mental health disorders. Few efforts have been made by pediatric psychologists to develop strategies for enhancing detection rates and management or to empirically evaluate the integration of pediatric psychology services into the primary care context. A conceptual model of factors influencing detection rates and ongoing management of mental health disorders within pediatric primary care is presented. Recommendations are made for more direct involvement of pediatric psychologists within the primary care context. 相似文献
